 ## [v1.89.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.89.0)

 Released at 2023-03-12

+**Update note: this release can crash with `cannot unmarshal timeseries from rollupResultCache` panic after the upgrade from the previous releases.
+This issue can be fixed by removing caches stored on disk according to [these docs](https://docs.victoriametrics.com/#cache-removal).
+Another option is to upgrade to [v1.89.1](https://docs.victoriametrics.com/CHANGELOG.html#v1891).**

 * SECURITY: upgrade Go builder from Go1.20.1 to Go1.20.2. See [the list of issues addressed in Go1.20.2](https://github.com/golang/go/issues?q=milestone%3AGo1.20.2+label%3ACherryPickApproved).

 * FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): increase the default value for `--remote-read-http-timeout` command-line option from 30s (30 seconds) to 5m (5 minutes). This reduces the probability of timeout errors when migrating big number of time series. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3879).
